A list of Goldbach compositions.

a) Given a range of integers by its lower and upper limit,
print a list of all even numbers and their Goldbach
composition.

b) In most cases, if an even number is written as the sum
of two prime numbers, one of them is very small. Very rarely,
the primes are both bigger than say 50. Try to find out how
many such cases there are in the range 2..3000.
